BOTTLE or. JAR CLOSURE.

larly adapted for use in connection with pro-- serve jars and the likefor preserving the contents thereof in an air-tight condition.

Theinvention contemplates, among other features, the provision of aclosure for jars which can be readily applied and as easily removed, theclosure being so arranged and.

cooperating with suitable means whereby the usual difliculty in removingthe closures from jars containing preserves and which have been packedaway for a great length of time, rangement which, without hurting orbruising the fingers, permits of readily removing the closure of thejar.

In the further disclosure of the invention reference is to be had to theaccompanying drawings, constituting a part of this specification, inwhich similar characters of reference denote corresponding parts in allthe views, and in which:

Figure 1 is a fragmentary front elevation of the jar and closure, thedotted lines indicating the unlocked position of the closure mechanism;Fig. 2 is a fragmentary rear edge of the jar body.

elevation; Fig. 3 is a vertical sectional view taken on the line 3-3 inFig. 1; and Fig. 4 is a horizontal sectional view taken on the line 4%in Fig. 1.

Referring more particularly to the views, I provide a jar body 10 and aclosure body 11 arranged to repose upon a seat 12 on the jar body 10,said closure body 11 having a circular depending flange 13 adapted tolie within the jar body and which aids in supporting the usual gasket orrubber ring 14 upon the closure body, the said ring being adapted tobear against the seat or upper The closure body has diametricallyopposed extensions 15 which project beyond the periphery ofthe jar bodyand which are provided with horizontal grooves 16 extending transverselyto the extension.

The jar body 10 is preferably provided with an annular groove 17 inwhich is arranged a band 18 encircling the jar body,

said band having a stud 20 formed therewith and projecting outwardlyfrom the periphery of the. jar body. Mounted to swing upon the band 18at the rear thereof is a member 21 of substantially U-shapedconstruction and which is adapted to pass over one of the extensions 15andhave a transverse portion thereof pass through one*of the grooves 16in the extension.

Mounted to turn upon the stud 20 is a locking member 22tconsisting, moreparticularly, of a substantially circular plate or disk 23 havin aneccentric or cam 24 thereon andalso provided with a suitable handle 25.The cam 2t has an annular groove 26 in the periphery thereof and amember 27 has it lower portion arranged to operate in the groove of thecam and its upper transverse portion adapted to pass through the groove16 of the other extension 15'so that the members 21 and 27 willeifectua-lly hold the closure body in sealed position on the jar bodywhen the locking members are operated, as will be hereinafter more fullydisclosed.

Now it will be apparent that when the main portion of the cam 24- liessubstantially above the point of pivotal connection of-the lockingmember with the stud, the securing member 27 will be loose relatively tothe cam so that it can be disengaged from the closure body and theclosure body then swung upon the member 21 and also disengaged therefromto permit of entirely removing the closure body from the jar body.Similarly, when it is desired to apply the closure body to the jar body,one of the extensions of the closure body is first engaged withthemember 21 so that a transverse portion of the member will pass throughthe groove of theeXtension. The closure body is then swung downwardlyupon the jar body so that the gasket or ring 14 will bear against theseat 12 and the other member 27 is then. arranged over the oppositeextension of the closure body so that the transverse portion of themember 27 will pass through the groove of the other eXtension. -Whenthis has been accomplished the handle 25 is grasped and the lockingdevice rotated relatively to the stud 20, thus causing the cam 24 toexert a pull upon the member 27 and force the closure body into sealedrelation with the jar body, said cam, when in its lowermost position.having its most effective locking action upon the member 27,

with the handle-25 adapted to bear against the member 27 when in itsfinal position, thereby limiting the locking. movement of the lockingdevice.- For this reason, the free end of the handle is preferablytwisted so that a portion thereof will lie fiat against a side ofthemember 27, as will be clearly seen by referring to Fig. 1. i V

From the foregoing description it will be clearly seen that thedeviceldescribed consists of few parts and that in the provision of thelocking devices set forth herein the cover or closure body can'beeffectually sebody and projecting beyond the periphery of the jar bodyat its upper end, a band encircling the jar body, a securing membermounted to swing on the band and extending into the groove of one of theextensions, a stud projecting from the band, a disk, mounted to rotateon the stud,,a grooved member on the disk and eccentric to the point ofpivotal connection of the disk with the stud, a second securing memberfor engagement with theother extension; of the closure body, said secondsecuring member cooperatingwith the eccentricmember, and a handleon thedisk whereby, when the disk is operated, said eccentric member willbeoperated to exert a pull on the last mentioned securing member andmove the closure body into sealed position on the jar .body, with thesaid handle having a stop member to limit the locking action of the saideccentric member.
